Scope of Professional Services

Schematic Design

After confirming with the client and other professionals, we will review the architectural concept design in detail and give advice on the engineering aspect if needed. A study is done on the possible MEP option to choose the most appropriate economical design. An outline schematic for each MEP system is prepared. We then establish a conceptual arrangement of the MEP system, coordinated with architectural and structural design. A location and space is selected for the MEP plant and equipment. After preparing a layout for each typical floor, we prepare a design and construction program.


After confirmation from the client on schematic design, we will carry out detailed engineering design and calculation. Tender drawing, specification, and schedule will be prepared.

Construction Stage

Issue drawing and specification for construction incorporating all changes agreed with contractor during negotiation. Review contractor’s drawing and equipment / material submission.
